I just started plugging my Solera into my garage outlet for the Winter. I noticed that the converter is made to run on trickle charge if nothing is being used. I figure on checking the battery weekly to be sure they aren't over charging, so far so good. One question I have however is the battery for the chassis hooked into the coach battery system? I'm wondering because the battery for the chassis is located under the driver's floor board. So to check it I'd need to open that area up for inspection also. But if it not hooked into the coach system then do I need to look at a battery tender for it? What do you think?

Good question, I was wondering the same thing. Yesterday, (Tuesday) I went out to drive my Solera and the battery wouldn't turn the motor over. I have a dedicated 30 amp line from my breaker box via a 10 ga. wire to a regular box like used in campgrounds. I know my rig was getting the full 110 volts. I jump started it from my truck battery. Here's the rest of the story and what I think happened. It has been several weeks since cranking the engine and the last time I used the camper I had left a GPS connected to the cigarette lighter under the ash tray which is hot all the time. If the GPS device ran the battery down, then it's not getting any charge from the 110 volt wire. Could be wrong about this tho....
Make sense??

Do you have a disconnect? I am not a MH guy and this is all I have on BCC issues; hope it helps.

We do run directly from the BCC chassis post to the battery under the driver floor. With this being said and the design of our BCC...With the unit plugged in AND the disconnect switch in the ON position(horizontal), the converter would charge the house batteries first. If and when they have been in a float charge state for a given period of time, the solenoid is supposed to be activated, connecting the chassis battery and allowing it to receive charge as well.
If I were you I would allow the chassis battery to drain a little bit, and then verify that it is indeed receiving the charge. If you would prefer not to pull up the floormat and such everytime, verify the cable we ran is connected to the battery under the floor the first time and then use the stud on the backside of the BCC to monitor voltage in the future.

IF you don't want to leave your rig plugged in all winter I suggest
the Battery Tender Jr. I have one on my truck, on my motorcycle and one
on my trailer. They're fully automatic and won't over charge and make
your batteries use any water. (Check water every couple months anyway
at first.)
DerbyCycles.net have the 6 or 12volt models for $25 with free shipping.
That's the cheapest I've found online or in a store.
I do not work for them! They are in the bluegrass state however

My truck battery is still the original going on 8 years old. It may strand me
tomorrow but today it cranks as good as new!
You really can maximize battery life by keeping them fully charged.

Where is BCC located on 2011 Solera? I keep the water level in coach batteries up using distilled water, so, unless the coach battery(s) are low, I should be getting chassis battery charged. Is this correct?

Also, and this is different subject, Are the MB computer codes available? I want to turn off the headlights and the owner's manual describes how to do this but it doesn't work. Have Googled this and unable to find computer codes. Vendors have for sale different diagnostic tools such as scan guage, etc. but I am not sure they will determine what the codes are...

I do have wires going through the coach battery compartment wall to the front of the coach, I asume these are going to the chassis battery? I'll check into it more today. I do have a battery tender JR. but if I can just keep the unit plugged in and get all the batteries charged through the converter? I'll see what I can find out today.

A 2011 Solera will have a different style BCC which operates differently than the current model. If you can pm me with your serial or VIN number I can see when it was built and figue out which BCC and where.

I have a 2012 Solera. I'm not exactly sure where the Battery Control Center is located. Could you also discuss where a trickle charge conection should be made to keep the coach and MB battery charged during winter storage. Thanks
